Mick Jagger went to a party at the Playboy Mansion. It was his first time visiting the debauched dwelling, so he slipped away to explore the house. (You know how rock stars love architecture and home furnishings.) Snooping around upstairs, he came upon a closed door and heard unusual noises on the other side. Curiosity got the best of Mick, so he flung open the door — to find Hugh Hefner and TV's Dennis Weaver in bed together, goin' at it like teenagers. Shocked, Mick shouted, “Hey, Hugh! Get off of McCloud!”
